Stationary bike

ABSTRACT

A stationary bike frame of fitness equipment comprised of a dancer pivoted to the frame and driven by a pair of pedals to engage in reciprocal motion at high frequency; a belt for the user to wear being drawn by the reciprocal motion of the dancer to create vibration at high frequency for fat reduction of a particular part of the body where the belt is worn by the user while simulating the motion of riding a bike.

BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention is related to fitness equipment; and more particularly, to a stationary bike frame that further provides fat reduction by high-frequency vibration for a specific part of the body of the user.

(b) Description of the Prior Art

Earlier deterioration of health and aging to the physical mechanism, or in serious case, karoshi, due to lacking in exercise are getting more popular particularly among the 9-5. Either the employer or the employee shall pay extra attention to the balance between working and resting.

Outdoor activities are usually restricted by the weather conditions, places, and the number of participants to become less self-motivated; therefore, indoor fitness equipment is widely accepted for people to work out for staying in shape. Most of the indoor fitness equipments, e.g., a running machine or a stationary bike, are designed to simulate outdoor activities.

However, the fitness equipment to work out essentially by cycling generally available in the market gets too monotonous and the user may lose the motivation to stick to the exercise after a while of use. Furthermore, fitness equipment with only a dedicated purpose provides limited results for a certain part of the body of the user. After a longer time of exercise, the muscles of that part are built up to become a flaw in staying fit to somehow fail the purpose of relying upon the fitness exercise.

SUMMARY OF THE INVENTION

The primary purpose of the present invention is to provide a stationary bike of fitness equipment that allows fat reduction of a particular part of the body of the user while working out by riding on it. To achieve the purpose, a dancer is pivoted to the frame and engaging in fast reciprocal motion as driven by a pair of pedals; a belt is provided to the dancer for the user to wear so that when the belt is driven by the reciprocal motion of the dancer, the vibration at high frequency provided by the belt on the particular part of the body of the user achieves the purpose of fat reduction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1 for the basic configuration of a stationary bike of fitness equipment, the stationary bike is essentially comprised of a frame 10, a seat 20 and a handle 30 adapted to the frame 10, and a pair of pedals 40 axially adapted to the bike frame. Wherein, a dancer 50 is pivoted to the frame 10 and is driven by the pair of pedals 40 to engage in fast reciprocal motion; two levers 52 are respectively and laterally provided to both sides of the dancer 50; and a belt 60 for the user to wear has both of its ends respectively coupled to both levers 52 as illustrated in FIG. 4. Accordingly, while the user steps alternatively upon the pair of pedals 40 to simulate riding a bike and wearing the belt 60, the belt 60 as driven by the reciprocal motion of the dancer 50 produces vibration at high frequency to provide fat reduction results on the part of the body of the user where the belt 60 is worn.

As illustrated in FIGS. 1 and 2, the pair of pedals 40 is axially provided to the middle section of the frame 10. A stem 11 is erected to the front section of the frame 10; the handle 30 for the user to have his/her both hands to hold onto is erected at the top of the stem 11; and the top of the dancer 50 and the stem 11 are pivoted to each other. An eccentric shaft 81 is provided at where between the dancer 50 and the pair of pedals 40, and a connection rod 82 is coupled to where between the eccentric shaft 81 and the bottom of the dancer 50. A resistance wheel 70 driven by the pair of pedals 40 is axially provided at the rear section of the frame for the pair of pedals 40 to drive through the resistance wheel 70 the eccentric shaft 81. Accordingly, as illustrated in FIG. 3, the dancer 50 engages in reciprocal motion due to the transmission provided by the eccentric shaft 81 and the connection rod 82.

A pedal tube 13 is provided at a fixed position in the frame 10 for both of the pair of pedals 40 and the eccentric shaft 81 to be axially disposed to the frame 10. The transmission respectively between the pair of pedals 40 and the resistance wheel 70 as well as between the resistance wheel 70 and the eccentric shaft 81 is executed by a chain wheel 41 and a chain 42. Each on both ends of the connection rod 82 is provided with an axial hole 821, and a shaft rod 51 is laterally provided at the where close to the lower end of the dancer 50. The connection rod 82 is inserted respectively with its both axial holes 821 into the eccentric shaft 81 and the shaft rod 51 to constitute the transmission between the eccentric shaft 81 and the dancer 50.

As illustrated in FIG. 5, a seat tube 12 extends from the rear section of the frame 10 for the seat 20 and the seat tube 12 to be inserted into each other with a seat post 21. Multiple locking holes 22 are provided on the seat post 21 and a locking rod 23 is provided at where both of the seat tube 12 and the seat post 21 are overlapped on each other. One end of the locking rod 23 is exposed out of the seat tube 12 and a compression coil 23 is provided at where between the locking rod 23 and the seat tube 12 to hold the locking rod 23 into the seat tube 12. Accordingly, by having the locking rod 23 to penetrate through one end in the seat tube 12 to be mutually engaged with locking hole on the seat post, the seat post 21 and the seat tube 12 are secured in position to each other while pulling out the locking rod 23 away from the seat tube 12 to disengage the locking rod 23 from the seat post 21 to facilitate adjustment of the relative positions between the seat post 21 and the seat tube 12. The locking rod 23 is then released for the compression coil 24 to push the locking rod 23 further into the seat tube 12 until the locking rod 23 is inserted into the locking hole 22 that the seat post 21 for providing fast adjustment of the height of the seat 20. Furthermore, a panel 90 to display the operation status of the stationary bike is erected to the frame 10.
